Characterization of soft stripe-domain deformations in Sm-C and Sm-C* liquid-crystal elastomers [PDF]
, 2008 The neoclassical model of Sm-C (and Sm-C*) elastomers developed by Warner and Adams predicts a class of “soft” (zero energy) deformations. We find and describe the full set of stripe domains—laminate structures in which the laminates alternate between ...

Dynamics of smectic elastomers [PDF]
, 2006 We study the low-frequency, long-wavelength dynamics of liquid crystal elastomers, crosslinked in the smectic-$A$ phase, in their smectic-$A$, biaxial smectic and smectic-$C$ phases. Two different yet related formulations are employed.

Ferronematic Liquid Crystal Polymers and Elastomers
MATERIAIS 2022, 2022 Liquid crystal polymers, through covalent bonding, combine the spontaneous long range orientational order of the liquid crystal state with the entropically driven random coil configurations of the skeletal polymer chains in a single material [1]. [...]

Optomechanical conversion by mechanical turbines [PDF]
, 2014 Liquid crystal elastomers are rubbers with liquid crystal order. They contract along their nematic director when heated or illuminated. The shape changes are large and occur in a relatively narrow temperature interval, or at low illumination, around the ...

Degradation-Induced Actuation in Oxidation-Responsive Liquid Crystal Elastomers
Crystals, 2020 Stimuli-responsive materials that exhibit a mechanical response to specific biological conditions are of considerable interest for responsive, implantable medical devices.

Effective behavior of nematic elastomer membranes [PDF]
, 2015 We derive the effective energy density of thin membranes of liquid crystal elastomers as the Gamma-limit of a widely used bulk model. These membranes can display fine-scale features both due to wrinkling that one expects in thin elastic membranes and due

Internal constraints and arrested relaxation in main-chain nematic elastomers
Nature Communications, 2021 Nematic liquid crystal elastomers (N-LCE) have a slow relaxation, which can prevent their shape recovery. Here, the authors examine mechanical hysteresis in a series of main-chain N-LCE to understand how the inherent nematic order retards and arrests the

Instabilities in liquid crystal elastomers [PDF]
MRS Bulletin, 2021 AbstractStability is an important and fruitful avenue of research for liquid crystal elastomers. At constant temperature, upon stretching, the homogeneous state of a nematic body becomes unstable, and alternating shear stripes develop at very low stress.

Morphing of liquid crystal surfaces by emergent collectivity
Nature Communications, 2019 Liquid crystal networks can morph their shape in response to electrical stimulus. Here the authors provide a detailed description of their deformation mechanism and introduce a method to observe the dynamic surface of liquid crystal elastomers.

Phase chirality and stereo-selective swelling of cholesteric elastomers [PDF]
, 2003 Cholesteric elastomers possess a macroscopic ``phase chirality'' as the director n rotates in a helical fashion along an optical axis $z$ and can be described by a chiral order parameter.
